  • 3+1 -dimensional thin shell wormhole with deformed throat can be supported by normal matter 
    Mazharimousavi, S. Habib; Halilsoy, Mustafa (The European Physical Journal C, Springer, 2015)
    From the physics standpoint the exotic matter problem is a major difficulty in thin shell wormholes (TSWs) with spherical/cylindrical throat topologies. We aim to circumvent this handicap by considering angle dependent ...
  • Canonical Acoustic Thin-Shell Wormholes 
    Jusufi, Kimet; Övgün, Ali (World Scientific Publishing Co Pte Ltd, 2017-02-16)
    In this paper, we model a canonical acoustic thin-shell wormhole (CATSW) in the framework of analogue gravity systems. In this model, we apply cut and paste technique to join together two spherically symmetric, analogue ...
  • Microscopic thin shell wormholes in magnetic Melvin universe 
    Mazharimousavi, S. Habib; Halilsoy, Mustafa; Amirabi, Zahra (European Physical Journal C: Particles and Fields, Springer, 2014)
    We construct thin shell wormholes in the magnetic Melvin universe. It is shown that in order to make a TSW in the Melvin spacetime the radius of the throat can not be larger than 2B0 in which B0 is the magnetic field ...
  • A particular thin-shell wormhole 
    Sakallı, İzzet; Övgün, Ali (Springer, 2017-02-09)
    Using a black hole with scalar hair, we construct a scalar thin-shell wormhole (TSW) in 2+1 dimensions by applying the Visser cut and paste technique. The surface stress, which is concentrated at the wormhole throat, is ...
  • Ph.D Defense- Studies on Thin-shells and Thin-shell Wormholes 
    Ali, Övgün (2016-07-18)
  • Rotating Thin-Shell Wormhole 
    Övgün, Ali (SpringerLink, 2016-11-08)
    We construct a rotating thin-shell wormhole using a Myers-Perry black hole in five dimensions, using the Darmois-Israel junction conditions. The stability of the wormhole is analyzed under perturbations. We find that exotic ...
  • Screening of the Reissner–Nordström charge by a thin-shell of dust matter 
    Mazharimousavi, S. Habib; Halilsoy, Mustafa (European Physical Journal C: Particles and Fields, Springer, 2015-07)
    A concentric charged thin-shell encircling a Reissner-Nordstr\"{o}m black hole screens the clectric / magnetic charge completely to match with an external Schwarzschild black hole. The negative mass thin-shell is shown to ...
  • Thin-shell wormholes from the regular Hayward black hole 
    Övgün, Ali (2016-01-07)
  • Thin-shell wormholes supported by total normal matter 
    Mazharimousavi, S. Habib; Halilsoy, Mustafa (The European Physical Journal C, Springer, 2014)
    The Zipoy-Voorhees-Weyl (ZVW) spacetime characterized by mass (M) and oblateness (δ) is proposed in the construction of viable thin-shell wormholes (TSWs). Departure from spherical / cylindrical symmetry yields positive ...
